Application filedseptember 7, 1925.

This invention relates to im )l'OVQDlGIliS in dilating douche nozzles. ihe object ot the inventibn is to cheapen the manufacture of such an article, render possible the eiiicient double fun tioning of some of the parts, and particularly, cheaply and efiiciently effect the assembling of various parts after their surfaces have been finished without injuring the non-corrodible quality of such surfaces.

The above and further objects will be pointed out more particularly in thejtollowing claims which are directed to an illustrative embodimentof th invention, solely for purposes of illustration and no limitation. The following specification desc es such an illustrative embodiment in connection with the accompanying dra which form a part hereof.

In the drawings,

Fig. 1 is a plan view of the complete nozzle in normal condition;

Fig. 2 is avertical axial section through the same with the dilator moved into operating position; l

Fig. 3 is a. view similar to Fig. 2 with the structure shown in dilated position;

Fig. A is a cross-section, partly an elevation taken through the plane of line TVIV of Fig. :2, looking in the direction or" the arrows drawn to an enlarged scale; I

Fig. 5 is a cross-section through the plane of line VV of Fig. 2, looking in the direction of the arrows and drawn to an enlarged scale; 1

Fig. 6 is a similar view taken through the staggered plane of line Vl--VI; and

Fig. 7 is a similar section taken through the plane of line VII-VII.

The nozzle comprises a relatively stationary sheath or tubular shell A adapted to protect the mouth of the organ to be irrigated from any moving parts. A tubula' stem B extends from the entrance nipple l. to the bulbous tip 2 axially through the shell A and provides a tubular spring reacting e2;- tension 8, extending out of the distal end of the shell A, within the locality embraced by a set of dilating arms C formed towards their inner ends with cam portions 4-, and extending through the cam nipple 5, secured by screw threads 6, into the distal end of the shell A.

The nipple 1 adapted to form a convenient coupling with a hose 7, in addition to the completed socket 8 securing it to the proximal end of the stem B, is provided with Serial No. 54,851.

spring sheath 9 or" a-size to telescope about the distal end of the shell A. The spiral compression spring 10 reacts between the nipple end of the sheath 9 and a cap 11 which butts against the rim of the proximal end of the shell A, so that the compression spring 10 normally exerts a force tending'to produce arelative axial movement between the stem B and the shell A, in other words, an outward movement or amovement towards the proximal end of the shell A for the stem B.

It is the function of this spring to hold the dilator arms C in contracted position, shown in Figs. 1 and 2. The dilation and contraction of the dilating arm C is eliected through the medium of a. longitudinal translation of the entire arms while the inner ends of the arms are held pivoted. An objective of the invention is to utilize the tubular stem B for its mechanical function in addition to its functioning as an induction duct for an irrigating fluid.

Functioning to overcome the contracting force of the spring 10 is an operator D, localized sur'liciently near to the proximal end of the shell A as to be located always outside of the cavity to be irrigated. In its movement, this operator D comprises a trunnion clip 15 fixed to the shell A mounting the pivot pin 16, upon which is pivoted the operating lever 17 having a bifurcated end 18 straddling the pusher lever 19, adapted to swing inside of the shell A and held against undesired outward movement by a heel 20. The lever 17 engages the pusher lever 19 when moved in one direction but moves free of lever 19 in the other direction to fold down along the shell A. Fig. 1 shows the lever 17 in folded-down position for packing, while 2 shows the lever in operative position for manipulation.

An important part in the present inven-- tion is the means associated with the'tubular stem B for imparting operative force from manipulation of the operator D to the dilator arms through the means of the tubular stem 13., It is to be understood that the entire nozzle structure is preferably fabricated from metal with all the parts having a smooth non-corrodible finish to permit of sterilizing and to prevent corrosion. In its manufacture, it is preferable that the entire stem B with its bulbous end 2 be finishedas a complete article of manufacture beforeassembling and that the assembling act not r dentations 24 involving the metal of the sleeve 23 which is forced down and into the metal of the stem B, forming therein nesting pockets 25; It is preferred that the sleeves 23 be formed of nickel silver and the stem B of brass, softer than the nickel. silver, so

that a localized flowing oi the parts takes place without constricting the duct within the stem B. This method of anchorage also precludes the mutilation of the surface of any of the parts to destroy its non-corrodible character.

The flange 26 of the part F directly cooperates with the pusherlt) to overcome the action of the spring 10 and to carry through a thrust against the heels 527 of the dilator arms C.

The art E is completed not by a flange 26 but a spider 28 provided with circumferentially spaced lock sockets 29 which terminate outwardly in pivoting bars 30. The heels 27 of the dilator arms terminate in hooks 31 which readily fit into the lock 1 sockets 29 to pivot upon the pivot bars 30,

the same being held in place against the removal of the dilating arms when the entire nozzle is assembled. Thus, it is to be noted that the central tubular stem B performs various functions.

What I claim and desire to secure by United States Letters Patent is:

In a dilating douche nozzle an inner tubular metal stem; an outer tubular shell; a compression spring; means for reacti-vely connecting said spring to exert a moving force relatively between said tubular stem and said tubular shelltendingto effect an axial movement of one within the other; dilator arms projecting out from the distal end of said tubular shell; an operator associated with the proximal end of said tubular shell; means for utilizing said tubular stem as a mechanical element responsive to said operator for effecting a positive movement of said dilators relatively to said tubular shell without impairing the functioning of said tubular stem as a fluid-conducting non corrodible duct, comprising a pair of'fianged metal sleeves axially spaced along said tubular stem, one directly engageable by said operator and the other engaging the ends of said dilator arms, which said sleeves have inwardly projecting localized indentations nesting with complementary surface indentations on said tubular stem.
